中文摘要：
通过对钠离子在高吸水性树脂吸水过程中的迁移行为的研究，得出：在树脂吸水过程中，钠离子会发生迁移或者说被氢离子交换，不会一直处于树脂网络中，但最终钠离子又回到网络中。钠离子这一行为决定了树脂的吸水过程。又通过不同水环境（一个是静止状态的去离子水，一个是流动状态的去离子水）的吸水过程的考察，进一步阐述和证实了钠离子的行为对高吸水性树脂吸水过程的影响。
英文摘要：
The moving behavior of Na＋ in the absorbing process of resin was studied. And it showed that Na＋ moved out or exchanged by H＋ , and they weren＇t always in the networks in the whole absorbing process, they were back to the networks finally. The behavior of Na＋ determined the absorbing process of resin. The process had been studied with two different of ways, one was in the resting deionized water, the other was in the flowing deionized water. And it was further discussed and confirmed that the behavior of Na＋ had effect on the absorbing process.
